AI Overview
converter is a core component in sulfuric acid production (Contact Process), using a vanadium pentoxide (
) catalyst to oxidize sulfur dioxide (
) into sulfur trioxide (
). This exothermic, reversible process typically occurs in a 4- or 5-pass converter tower, often with vertical or horizontal catalyst beds, operating under precise temperature control to maximize conversion rates.

How do you convert SO2 to SO3?
In this step, the conversion of sulphur dioxide to sulphur trioxide is done by mixing SO2 with atmospheric oxygen to oxidise it to form SO3 in the presence of V2O5 as a catalyst. This reaction occurs at the following conditions: Sulphur dioxide and oxygen (from air) are mixed in the ratio 1:1 by volume.

Is the conversion of SO2 to SO3 reversible or irreversible?
Conversion of SO2 into SO3 is a reversible process. The process of formation of SO3 is an exothermic process. Hence, we require a specific amount of temperature just to burn sulphur dioxide in presence of air to convert it into sulphur trioxide. V2O5 is used as a catalyst in the reaction.
In the formation of SO3 by contact process, the conditions used are
